Only thing I didn't try tightening is the support brace in the center as I couldn't find what type of bolt that was and it was getting dark.

I just tightened the front support a little with a breaker bar. Didn't know if I should go tighter. It was pretty loose but idk if that's the bolt or just the breaker bar doing its job. Is there a torque spec I should get that to with a torque wrench?
